To all whom it may concern:

Be it known that I, CLAUD D. CURRY, of

Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Paper-Associating Machines; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Th1s invention relates to paper associating machines, and more particularly to 1mproved means for inserting or stufiing' newspaper parts or sections.

()ne. object of the invention is to provide a machine ofthc character specified which will operate to rapidly and accurately insert an inner part or section of a newspaper -or other collection of sheets, into an outer part or section and deliver the paper thus staffed from the machine.

; A further object is to provide improved means for opening an outer part or tron comprlsmg a series of folded sheets,

and holding the same open for the reception of an inner .part which also comprises a series of folded sheets.

A further object is' to provide mechanism which will operate automatically and mechanically to opena folded newspaper part or section and positively hold the same open; which will then insert a part or section into the said open part or section, and which will then release the newspaper thus stuffed and discharge the same from the machine. 1

A furtherv object is to provide, in anewsstuffing: machine, means for-preventin the collapsing of the papers on account of their own weight. and thus prevent the clogging of the machine.

A further object is to provide simple and efficient devicesfor mechanically opening a folded newspaper part or section.

With these and other objects in view, the

invention consists in certain novel features of construction and eombinations of parts as hereinafter set forth and pointed out in theclaims.

ln the accompanying drawings;

1 representssuitable frame-work, upon which two hoppers 2. 3 are located and these hoppers are provided with inclined bottoms *4 which extend partially across the lower ends of the same and terminate appreciable distances from the inner side walls of the hoppers. A verticalnshaft 5 is mounted in the framework between the hoppers 2-'3 and at its lower end, carries a horizontallyceives motion from a bevel gear 10 on a horizontal shaft 11. for continuously driving the disk 6. r

Below the disk 6 and at respective sides of the axis thereof, horizontally-dispcsed cylinders 12 and 13 are located. Each cylinder is provided with a shaft 1 1, one end of which projects beyond .the cylinder and forms a journal mounted in a suitable bearing in the framework, and to the journal of each shaft 14, a gear 15 is secured to receive motion from the driving mechanism. The inner end of the shaft 15 of each cylinder terminates within the latter and is made with'a socket 16 which receives the inner end of a short shaft 17 secured to the framework. The shaft l l of each cylinder is thus journaled at one end in a bearing on the framework and 'at the other "end on the inner end of the "fixed shaft 17 It maybe her'e stated that the mechanisms at respective dides of the vertical center of the machine, arcduplicates in construction and mode of operation, but the two sets of devices are arranged in reverse positions at respective sides of the vertical center of the machine.

Each cylinder 12-13, is prpvided in its peripheral wall near one end, with an opening; 18 for the accommodation of a mechanical withdrawing device or needle box 19 as shown movable head 2'7.

in Fig. 1 and in detail in Figs. 7 and 8. In constructing t is Withdrawing device or needle box, I provide a rectangular frame 20 which embraces and. slides ona bloc-l: 21 secured to the fixed shaft section 17 so to be guided in its longitudinal movements by said block. -The frame 20 is provided at one end with an inclined enlargement 22, the outer tace of which is disposed at an angle of approximately to to the axis of the frame 20. enlargement 22,

able heao t in the enlargement 22 of the frame 20. Levers 30 are pivotally' supported between their ends, at diametrically opposite portions on the frame 20. The inwardly projecting arms of these levers carry pivotal blocks 31 mounted to move in ways 32 at the inner end of the movable head 27, and the outwardly projecting arms of said levers are pivotally attached to a cross hear 33 mounted on the frame 20 and provided with ribs to move in guide-grooves 85 in said frame. It is apparent that if the cross head bemoved on the frame 20, motion will be imparted, through the medium of the levers 30 to the movable head 27 for the purpose of pro ecting or withdrawing the pins or needles 25. For thus Zoperating the cross head and for sliding the frame 20 longitudinally, each cylinder (12 andIS) is provided at one end with two cam grooves 36 and 37, one within the other. A pin 38 projecting from the sliding frame 20 enters the larger outer cam groove 36 anda pin 39. pr0jecti11g'-.from the cross-head 33' cooperates with the inner cam groove 37.

As shown in Fig.3 of the needle box,- or withdrawing devices 19 above described, are located at one end of the cylinder 12-and at the opposite end 'of the cylindci" Hinged fingers, 51 ardlocated near the needle boxes or withdrawing dedrawing the I l l sas es vices l9 and are held up in engagement with the bottom paper secticus in the hopper. I )y the peripheral portions of the disks 5. It

will be observed in Fig.3 of the drawing,

that the peripheral portion of the disk 6 is vice 19.

The cams 36 are so formed that they will cause the needle box 19 to be projected toward the'lower ends of the hoppers 2? and subsequently withdraw them, and the cams 37 will so cooperate with the cross heads as to cause the needles 25 to be projected and afterward withdrawn. The cams 3'(l-37 of the respective cylinders are so disposed that the needle boxes or withdrawing devices in one cylinder (say the cylinder 12) will. operate in advance of those in the other 'cylinder, so that an outer part or section of sheets will be withdrawn from one hopper in advance of the withdrawal of an inner part or section from the other hopper.' Thusthe needle box in one end of theeylinder 12 will be projected .upwardly toward the folded section of papers lying in the bottom of the hopper 2 and the needles of this needle box will be thrust upwardly in an inclined direction previously explained, and caused to engage the bottom folded paper section. As the cylinder and its cams continue to turn, the needle box w1ll be caused to retreat and thus to pull the,

wardly into the slot f the horizontal disk 6. "The cam 37 in the cylinder will afterward operate L'OWVltlKlltUtf the needles from the paper section. The rotation of the disk 6 will first cause itsfinger 8 to pass over the paper section, and during the rotation ofthe disk, a portion thereof will become disposed over a portion of the folded paper section. As the disk 6 turns, its finger portion 8 will engage the finger 51 which had been dropped and raise said finger-to its normal horizontal position. During such raising of the finger 51,"any portion of a superimposed paper section which may have descended with? the lowermost paper section being fed from the hopper, will be raised and its entanglement with the disk 6 effectually prevented. The paper section having been partially removed from the hopper, will now be met by a tumbling blade 40 carried by the cylinder and'deflected by said blade sons to be fed between the cylinder and a feed roller 41. 'The cylinder is provided with shoes 42 of leather or other suitable material, which are so placed that they will arrive approximately opposite the feed roller assets 41 after the paper section reaches the latter. The coiiperation of the shoes 42 on the cylinder with the feed roller 41, will cause the pa per section to be fed downwardly and said paper section willloe made to follow the cylinder by means of curved guides 43. After conforming to the contour of the cylinder throughout a portion of their length, the guides 43 project downwardly in a straight diagonal direction an terminate adjacent to rollers 44 secured to a shaft 44 located at one side of the vertical axis of the machine. Rollers 44 are similarly located at the other side of the vertical axis of the machine and the guides 43 and feed roller 41 are also duplicated so as to cooperate in the same manner as above described with the cylinder 13 and the paper sections removed iii-the same manner as previously explained from the hopper 3. Rollers are located on shafts 46 adjacent to the cylinders 12 and 13. Feeding tapes 47, coiiperating with the respective cylinders 12 and 13, pass over th rollcrs 44 and 45 at respective sides of tl-ieyer-ticaI axis of the machine and are driven by power applied to the shafts of the rollers 44. Shafts 48 are located above the rollcrsee and carry rollers 49, which cooperate with the tapes 47 to feed the paper section i. ownwardly over the rollers 44.

Guides 50. areh ung on the shafts 48 and extend from the longitudinal center of the machine approximately to the cylinders 12 and 13, so as to cooperate with the tapes in directing the paper sections downwardly between the rollers 44. V

Reverting now to the tumbling blade 40, its construction and mode of operation will be explained: Each cylinder (12 and 13) is provided with an elongated slot or opening,

' 58 behind which a shaft 54 is located and ;;prov1ded with crank arms 55, having ournals 5657 mounted in the respective heads of the cylinder. On the shaft 54, theblade 40 is hinged and pressed in one direction against stops 59 on the shaft, by means ofsprings 60. it will be understood that each cylinder is provided with a tumbling blade and are duplicates in construction and mode of operation. Near one end of each cylinder, a ring 61 is located and provided atv diametrically opposite points with recesses 62 -63. A cross head 64 is located at the end of the journal'lfi of each shaft 54 and from the respective ends of this cross head, pins 65 project into the ring 61. Gears 66-67 are mounted on suitable studs secured to the.

framework adjacent to the ring 61, andeach of said gears is provided with ajlug 68 disposed within; said ring' 61. Teshapcd trackways-69 are located adjacent to the respec- "tiveendsof the cylinders, and each comprises 'a vertical'portion 70 located between the cylinders and lateral portions 71 projecting upwardly over the cylinders. With these ter, by the engagement ofthe rollers 72 with the upper members 71 of the trackway 69. When the blade, movin r with cylinder, deflects the paper section ant causes it to be fed under the feed roller 41 as previously explained, one of the lugs 68 will engage one of the pins 65 on. the shaft 54 and force the same into one of the recesses (62 or 63) in the ring 61. As the cylinder continues to turn, the engagement of one of the pins on the shaft 54 with the riecess in the ring 61 will cause the shaft 54 and the blade 40 to be turned over. When, during the rotation of the cylinder, the tumbling blade reaches the other recess .in the ring 61, one of the ins 65 will enter the other recess (62 or 63) and the blade will again turn so as to place it in proper position to deflect the next paper section coming from the hopper. After the blade 40 has been thus turned, it will be prevented from enga ement with the adjacent cylinder by the riding of the pins 'or rollers 72 on the vertical portion 70 of the tracks way 69, the blade-being thus pressed back against the resistance of the springs 60.

I have hereinbefore described the construction and operation of the mechanism which will take a folded paper section from the bottom of a hopper and deliver the same, with the folded edge at the bottom, at the rollers 44. The mechanisms for the duplicate sets are so timed that after an'outer paper section has been fed from one hopper downwardly past the rollers 44, the inner paper section will be fed in the same manner and made to follow the first-fed section, the purpose being to ,insert the said inner paper section into the outer paper section. Before the inner paper section can be inserted into the outer section, the latter must be opened to receive it, and after the paper sections shall have been stutl'edfi'they must be discharged from the machine. For these purposes, the mechanism now to be described will be employed.

Some distance below the rollers 44, two shafts 7 3 are mounted in the framework and tend from the rollers 44, downwardly between the disks 75, said guide plates terminating at their lower ends somewhat below the axes of the disks 75. Rollers are mouutedon the shafts 81. located in proximity to the guide plates 70. Tapes 82 pass over rollers 45 near one end of each shaft 16 and, extending downwardly parallel with the tapes 117, pass over rollers 4141. on the shafts 44 then downwardly and under the rollers S0 and finally back to the rollers 15 on shafts 16. Tapes 8t pass over rollers at one end of each shaft 14;, and over rollers at one end of each shaftSl, said tapes 84 also passing over rollers 85 supported by brackets 86 secured to the framework.

A paper section is fed downwardly by the action of the tapes above described and after passing between and beyond the lower ends of the guide plates 7 0, will rest on fingers 87 projecting from a shaft 88 located below the vertical disks 75. Adjacent to the shaft 88, another shaft 80 is located, and to the shafts 88 and 89, the lower ends of guide strips 00' are secured, the upper ends of said strips be ing supported by transverse rods 91 located short distances outwardly from the outer face of the disks 75.

In order to prevent the paper section from collapsing or crowding upon itself by dropping too heavily upon the fingers 87, I provide arms 92 pivotally supported at the lower end on the shaft 88 and provided at their upper ends with fingers 93 adapted to cooperate with stops 94: supported by one of the'rods 9.1. The arms 92 are provided with a shoulder 95 to be engaged by can). 06 on a shaft 97. The gearing which operates the shaft 97 is so turncd'that the cam 96 will force the arms 02 toward the stops 0%: and catch the descending paper section before the latter reaches the lingers 87, and as the cam 96 passes the shoulder 05, the arms will be retracted by a spring 98 so as to release the paper section and permit it to drop lightly-upon the fingers 87 Transverse bars or brackets 99 reach the upper front corners of a paper sec-.

tion resting between the disks.

In constructing each needle box 101, a head 102 is made integral with the inner end of the arm and provided with a beveled forw rd end, to which a skeleton head 103 is adjustably secured. This skeletoi'r head is provided with a number of inclined holes 104 for the passage of a number of needles 105, These. needles are carried by a head 106 movableon the arm 100. Bellare fixed to the framework some distance laterally from esaoee cranks 107 are pivoted to the. arm 100, and these hell-cranks carry pivoted blocks 10S movable in ways 109 at the ends of the movable head for operating the latter to project or withdraw the needles carried thereby, The bell-cranks 107 are connected by a rod or bar 110 (Fig. 8) and the latter 1S provided with a crank-arm 111. The outer end of each arm 100 adjustably connected, by means of a screw 112, Witlra yoke 113 having an elongated slot 114 forthe passage of a shaft 115 (Fig. 1). Two shafts are mount cd near respective sides ofthe framework, and to each shaft 115, a cam wheel 116 is secured and provided with cam grooves 117 and 118, one within the other. Each yoke 113 is provided with a pin 119 which cooperates with the larger cam groove 117, for moving the arm 100 longitudinally and projecting near the needle box toward the folded paper section or retracting it therefrom. Each yoke 113 is madewith a recess 120 for the accommodation of a longitudinally movable L-shaped bar 121, and with an elongated slot 122 for the passage of a pin 123 projecting from said L-shaped bar, said pin 128. being thus in phsition to cooperatewith the smaller cam groove 118 of the adjacent cam wheel 116. A rod 124 is adjust-ably secured to one end of the t.- shapcd bar 121, and to the end of said rod, an Lshapcd rod 125 is hinged. The arm 126 of the rod 125 is provided with a lateral projection 127 pivotally attached to the crank arm 111 on the-rod 110 which connected the bell cranks 1Q". it is apparent that with such construction, motion will be imparted from the cam-wheels to the mov able heads of the needle boxes and the needles'thus projectedto engage the paper section or retracted to withdraw the needles from the paper.

The mechanism above described forepcn ating the needle boxes 101 is so timed and proportioned that the two needle boxeswill be simultaneously moved toward each other and caused to confine the corner of the folded paper section between them, after which the needles will be projected andn ade to engage the paper section. in order t' in. sure such engagement of the noodles with paper section so that when the needle bones are withdrawn, the corners of the folded paper section will be moved laterally, the

devices now to be described will be em-.

ployed: the journal bearings of gears128 are supported by brackets 129 secured tothe framework and receive motion from gears 130, the shafts of the latter being provided with bevel gears 131 to receive motion from bevel gears 132. with projections 133 which cooperate to rasp the paper section and pull the same faterally with suliicient force to causev the The gears 128 are provided inclined needles to properly penetrate the 1 viously explained.

and in the aths of ,these shoulders, rollers 135 (Fig. 1 are disposed, said rollers being carried at the free inner ends of arms 136 secured-to the fixed transverse bars 99.

The paper section having been disposed between the disks 7 5 and made to rest with its folded lower edge upon the fingers 87, the needle boxes 101 will advance to grasp the corner of the paper section between them and the needles caused to penetrate the members of the folded paper section, all as pre- The needle boxes will now be retracted to cause the corners of the members of the paper section to separate from each other, and afterward, the needles will be. withdrawn from the paper by the action of the cam 11S and the devices which cooperate therewith. hen the corners of the folded members of the paper section shall have been moved away from each other, the nose or finger portions 77 of the disks 75 willapproach the separated corners of the paper section members and, asthe shoulders 134 on said fingers 77 pass over the rollers 135, said fingers will be depressed sufficiently to cause them to enter between the members of the folded paper section. Now as the disks continue to rotate, they will'become disposed on the inside, of or between the members of the folded paper section, and thus said paper section w1ll be opened out and, supported by the guide strips 90, be in position to receive an inner aper section between its' members. When t e operations on an outer paper section coming from one of the hoppers, shall have been completed, an inner paper section or insert will arrive between the guide plates 79'and will drop down between the disks and therefore into the opened-out outer paper section. The stuffed paper sections are now resting upon the fingers 87 and these fingers are maintained in a horizontal position to sus tainthe. paper section or sections during the operations aboi e described, by the engagement of a roller 13? (Fig. 2) on an arm 138 secured to shaft 88, with a cam 135) on the shaft 97. \Vhen the stalling operation shall have been completed, 'the cam 139' on the shaft 97 will have moved to a position to release the arm 138 on shaft 88, when a spring 140 attached to said arm 138 will cause the shaft 88 to turn and the fingers 87 carried by this shaft, to descend and thus remove the support for the stuffed paper sections. Opposite the shaft 97, another shaft 97 is located, and these shafts 97 and 97 carry clutch arms orjaws 1'41, -The shafts 97 and 97 are-geared [to rotate-- in opposite directions sojt'nat the armspn'aws 141 movin toward each other, will-cooperate to grasp the stuffed paper sections and move the same downwardly between positively-driven feed rollers 142, 143, the latter being supported by a spring-pressed or yielding bracket 144. The stuffed paper sections are fed by the rollers 142-143 to one of a series of rotating delivery lingers 145, by means of which latter, the paper is placed upon a traveling conveyer 146 which will carry the same from the machine.

The gearing by means of which the various parts of the mechanism are driven, is shown diagrammatically in'Fig. 1 of the drawing power being applied to one of the shafts 115.

lVhile my improvements are designed for stuffing newspapers they may be employed also for assembling papers of a different character, such for example, as signatures for books or magazines.

Various slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope and hence I do not wish to restrict myself to the precise details herein set forth. I
